Final answer:
The statement that a diet with 30 grams of fiber is prescribed for a client with diverticulosis is true. Fiber helps in easing bowel movements and prevents constipation, which is beneficial for those with diverticulosis.
Step-by-step explanation:
The recommendation for a client with diverticulosis to consume a diet high in fiber is indeed true. A high-fiber diet with about 30 grams of fiber daily is generally recommended as it helps to increase stool bulk and prevent constipation, which can reduce the pressure in the colon and the risk of developing diverticula or worsening existing diverticulosis. The statement about enzymes that digest cellulose cannot bind to the cellulose due to altered active sites, thus adding bulk to the food and easing bowel movements, is a general comment on how fiber aids digestion and is not specifically related to diverticulosis treatment. Regarding carbohydrates, it's important to consume them because they are necessary for biological functions, for example, they provide energy for the body's cells.
